It will be the soap you are using, you are NOT suposed to use anything like soap, 'feminine hygeine' products and so on, I can't say exactly what is best but I would think that a medical soap with the right PH - basicaly in doubt ask at the chemist, also do the research on whatever you use because often even people in chemists do not know how to help take care of the vagina and don't realise how much things like soap, tampons, body sprays etc. can damage the vagina and harm the vulva.

i used to suffer from a really sore vagina for years until the doctor evenutally asked if i washed there with soap and i said of course it'd stink otherwise! but apparantly ur only supposed to use warm water cos ur vagina has its own bacteria system which cleans it properly, soaps even hypoallergenic ones simply kill this bacteria therefore stopping ur vagina from being healthy.

That is absolutely correct. Wash with warm water and nothing else. All of those feminine hygiene products on the market are making a nice buck off of women who don't know any better. I saw a man in a store 2 weeks ago talking to his wife obviously on his cell phone as he tried to find the right brand of douche for her and I had to bite my tongue to not make a snide remark on the side just loud enough so he could her about "don't they know that women shouldn't douche?" Leave the feminine hygiene products on the shelf in the store and keep the soap and other irritating things away from your actual vagina when bathing.
